What it detects

This rule flags PowerShell module activity where an obfuscated command line invokes cmd to run clip.exe and uses chained actions that include a clipboard-related payload pattern. Obfuscated execution like this can help attackers conceal the true command intent while leveraging clip.exe for indirect data handling. The detection relies on PowerShell module telemetry capturing command payload strings and matching a specific obfuscation/clip.exe plus clipboard payload regex.
